Section 1286.230  Checking Approved Evidentiary Instruments for Continued Accuracy

To ensure the continued accuracy of approved evidentiary instruments, a BAT or automated system shall perform accuracy checks.

a)         Checks shall be performed at least once every 62 days.

b)         Checks shall consist of at least two tests of the instrument in which the instrument quantitates a reference sample.

c)         Approved evidentiary instruments must quantitate a reference sample within 10 percent of the reference sample's value, as adjusted for environmental factors.

d)         The accuracy check results shall be recorded in the instrument's logbook or internal memory, or in the central repository.  The automatic accuracy checks or accuracy checks performed remotely will not be entered in the logbook.  If the accuracy check was performed by a BAT at the instrument location, the accuracy check results shall be recorded in the instrument's logbook.

e)         The Director or his/her designee, at his/her discretion, may remove any approved evidential instrument located in any department, agency, or sheriff's office from active service due to lack of use.
